* Use a flag to signifiy that all sources need updatingChris Robinson2011-07-111-2/+7
|
* Use a Lock/UnlockDevice function instead of locking a NULL contextChris Robinson2011-07-061-4/+4
|
* Don't modify the source's WetGain[HF]Auto because of a slot's stateChris Robinson2011-07-061-4/+0
|
* Store and use the send slot in the source paramsChris Robinson2011-07-051-0/+5
|
* Scale the WetGain parameter directly instead of on each applicationChris Robinson2011-07-051-1/+2
|
* Apply wet path calculations with their dry path equivalentsChris Robinson2011-07-051-86/+112
| | | | | | The auxiliary slot (and related effect) properties are retrieved at the same time as the source properties. This will help ensure each property is accessed from the source and slot only once.
* Use a helper to tell if an effect type is reverbChris Robinson2011-07-051-5/+2

* Read the source's RoomRolloffFactor onceChris Robinson2011-07-051-9/+10

* Properly save the original FPU state when using _controlfpChris Robinson2011-07-021-1/+2
|
* Do air absorption with linear gain valuesChris Robinson2011-07-011-11/+1
| | | | This copies the way the calculation is done with the wet path
* Avoid accessing source properties more than once when updating parametersChris Robinson2011-07-011-6/+11
|
* Rename Suspend/ProcessContext since they are locking a mutexChris Robinson2011-06-301-4/+4
|
* Declare some variables closer to where they're usedChris Robinson2011-06-291-10/+12
|
* Add a source property to skip channel virtualization for multi-channel buffersChris Robinson2011-06-291-17/+47
| | | | | | | | | With virtualization disabled, channels are mapped directly from input to output and any input channel that is missing an output is dropped. Any virtualization effects (such as HRTF filters) for positional cues are also skipped. The idea is to allow applications a way to play pre-filtered audio that channel vitualization effects could interfere with.
* Select the correct resamplerChris Robinson2011-06-281-4/+8

* Don't bother with a per-context lock for disconnecting devicesChris Robinson2011-06-261-3/+0

* Select the mixer during a source updateChris Robinson2011-06-251-0/+8
|
* Use 'Distance' for the unclamped distance value, since the clamped value isChris Robinson2011-06-211-20/+20

* Calculate wet gain when neededChris Robinson2011-06-181-5/+4
|
* Do stereo duplication in two passesChris Robinson2011-06-171-52/+44
| | | | First using the rear channels, then using the normal stereo channels
* Don't suspend individual contexts when updatingChris Robinson2011-06-161-3/+0
|
* Use a minimum phase HRTF data setChris Robinson2011-06-031-7/+13
| | | | This reduces the coefficient size from 128 down to 32, with a set of delays
* Add a 5.1 device format that uses side channels instead of backChris Robinson2011-05-281-0/+11

* Clear HRTF coefficients for the LFE channelChris Robinson2011-05-251-1/+9

|
* Add an option to reverse Z panning of mono sourcesChris Robinson2011-05-071-3/+3
| | | | | | | | | | | Applications that are not built around OpenAL's orientation system need to convert their given vectors to it. Depending on how this is done, it can lead to proper stereo (left-right) panning with improper surround sound (front-back) panning, which thusly sounds correct with stereo output and incorrect with 4+ channel output. This option is intended to help fix playback of such applications on surround sound systems, without having to resort to forcing stereo output.
* Combine duplicate arraysChris Robinson2011-05-061-64/+31
|
* Skip LFE with HRTF outputChris Robinson2011-05-061-0/+9
|
* Use the panning algorithms to build the multi-channel source matrixChris Robinson2011-05-061-92/+132
| | | | | This prevents the stereo-duplication option from working. It should hopefully be restored soon.
* Remove some redundancyChris Robinson2011-05-061-6/+5
|
* Minor source update fixesChris Robinson2011-05-061-3/+3
|
* Remove the head_dampen optionChris Robinson2011-05-061-14/+0

* Mark a couple more pointers as restrictedChris Robinson2011-05-061-2/+3
